Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X100S and the Ricoh GR IIIx? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Fujifilm X100S and the Ricoh GR IIIx. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

The X100S can be obtained in two different colors (black, silver), while the GR IIIx is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Ricoh GR IIIx is notably smaller (28 percent) than the Fujifilm X100S. Moreover, the GR IIIx is substantially lighter (41 percent) than the X100S. In this context, it is worth noting that neither the X100S nor the GR IIIx are weather-sealed.

Concerning battery life, the X100S gets 330 shots out of its Fujifilm NP-95 battery, while the GR IIIx can take 200 images on a single charge of its Ricoh DB-110 power pack. The power pack in the GR IIIx can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The GR IIIx was launched at a somewhat lower price (by 23 percent) than the X100S, which makes it more attractive for photographers on a tight budget. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a slightly smaller sensor, the GR IIIx offers a higher resolution of 24 megapixels, compared with 16 MP of the X100S. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.91μm versus 4.80μm for the X100S). However, it should be noted that the GR IIIx is much more recent (by 8 years and 8 months) than the X100S, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Ricoh GR IIIx implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR IIIx for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Fujifilm X100S are 24.5 x 16.3 inches or 62.2 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.7 x 33.2 cm for very good quality, and 16.3 x 10.9 inches or 41.5 x 27.6 cm for excellent quality prints.

The Fujifilm X100S has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Ricoh GR IIIx are ISO 100 to ISO 102400 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. The X100S uses Fujifilm's X-Trans layout of photosites, while the GR IIIx employs the more common Bayer array.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the X100S has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GR IIIx relies on live view and the rear LCD for framing. That said, the GR IIIx can be equipped with an optional viewfinder – the GV-3. The following table reports on some other key feature differences and similarities of the Fujifilm X100S, the Ricoh GR IIIx, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The X100S has one, while the GR IIIx does not. While the built-in flash of the X100S is not very powerful, it can at times be useful as a fill-in light.

The Ricoh GR IIIx has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Both the X100S and the GR IIIx have built-in prime lenses. The X100S has a 35mm f/2.0 optic and the GR IIIx offers a 40mm f/2.8 (focal lengths in full frame equivalent terms). Hence, the Fujifilm provides a wider angle of view than the Ricoh. The X100S offers the faster maximum aperture.

Concerning the storage of imaging data, both the X100S and the GR IIIx write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Fujifilm X100S and Ricoh GR IIIx and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GR IIIx offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the X100S does not provide wifi capability.

The GR IIIx is a recent model that features in the current product line-up of Ricoh. In contrast, the X100S has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the X100S was succeeded by the Fujifilm X100T. Further information on the features and operation of the X100S and GR IIIx can be found, respectively, in the Fujifilm X100S Manual (free pdf) or the online Ricoh GR IIIx Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Fujifilm X100S or the Ricoh GR IIIx – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Fujifilm X100S:

• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Faster burst: Shoots at higher frequency (6 vs 4 flaps/sec) to capture the decisive moment.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/2.8).
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• Longer lasting: Can take more shots (330 versus 200) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More heavily discounted: Has been available for much longer (launched in January 2013).

Arguments in favor of the Ricoh GR IIIx:

• More detail: Has more megapixels (24 vs 16MP), which boosts linear resolution by 23%.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1037k vs 460k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (109x62mm vs 127x74mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 183g or 41 percent) and is thus easier to take along.
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was released into a lower priced segment (23 percent cheaper at launch).
• More modern: Reflects 8 years and 8 months of technical progress since the X100S launch.

If the number of relative strengths (bullet points above) is taken as a guide, the GR IIIx is the clear winner of the contest (14 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Fujifilm X100S and the Ricoh GR IIIx place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the X100S or the GR IIIx. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
